Pubblicati aggiornamenti correttivi per i pacchetti Samba 4.23.2, 4.22.5 e 4.21.9 che risolvono una vulnerabilit\u00e0 (CVE-2025-10230) nell'implementazione del server di risoluzione dei nomi WINS, consentendo l'esecuzione remota di codice sul server senza autenticazione. Il problema \u00e8 stato classificato con il massimo livello di gravit\u00e0 \u2014 10 su 10. <\/p>\n

La vulnerabilit\u00e0 \u00e8 causata dalla mancanza di un'adeguata verifica dei valori trasmessi prima dell'avvio dell'applicazione indicata nel parametro \u00abwins hook\u00bb. Questa applicazione viene avviata tramite il comando \u00absh -c\u00bb ogni volta che il nome viene modificato tramite WINS. Quando si utilizza WINS in un controller di dominio<\/a> Active Directory, i nomi NetBIOS trasmessi come argomenti della riga di comando all'avvio dell'applicazione hook non venivano ripuliti da caratteri speciali, consentendo l'esecuzione di comandi shell arbitrari specificando un nome NetBIOS formattato appositamente nella richiesta al server WINS. cmd = talloc_asprintf(tmp_mem, \u00ab%s %s %s x %ld\u00bb, wins_hook_script, wins_hook_action_string(action), rec->name->name, rec->name->type, (long int) rec->expire_time); \u2026 execl(\u00ab\/bin\/sh\u00bb, \u00absh\u00bb, \u00ab-c\u00bb, cmd, NULL); <\/p>\n

Un client senza autenticazione pu\u00f2 inviare al server WINS un pacchetto di registrazione e richiedere qualsiasi nome NetBIOS, non superiore a 15 caratteri. Non viene effettuata la pulizia di caratteri come \u2018\u2019 e \u2018;\u2019 nel nome. Pertanto, durante l'esecuzione dell'handler hook, la trasmissione di un nome come \u00abname;id>file\u00bb porter\u00e0 all'esecuzione dell'utilit\u00e0 \u00abid\u00bb e all'invio dell'output al file \u00abfile\u00bb. <\/p>\n

La vulnerabilit\u00e0 si manifesta su sistemi in cui nel smb.conf \u00e8 impostato il parametro \u2018wins hook\u2019 durante l'utilizzo di un controller di dominio attivo. server<\/a> WINS (disattivato per impostazione predefinita e richiede l'attivazione del parametro \u00abwins support = yes\u00bb). L'utilizzo del server WINS in sistemi senza controller di dominio non manifesta la vulnerabilit\u00e0. \u00c8 possibile verificare lo stato della nuova versione del pacchetto o la disponibilit\u00e0 di una correzione nelle distribuzioni sulle seguenti pagine: Debian, Ubuntu, Fedora, SUSE\/openSUSE, RHEL, Gentoo, Arch, FreeBSD, OpenBSD e NetBSD. <\/p>\n

Negli aggiornamenti pubblicati di Samba \u00e8 stata risolta anche una vulnerabilit\u00e0 meno grave (CVE-2025-9640) che porta a una perdita di memoria non inizializzata. Il problema si manifesta nel modulo vfs_streams_xattr in caso di fallimenti nell'allocazione della memoria, che possono essere causati da operazioni di scrittura che creano aree vuote nel file. La vulnerabilit\u00e0 pu\u00f2 essere sfruttata da un utente autenticato.
